How to prime Graco Paint Sprayer?
- R
  reidjulieAug 17, 2025
  To prime your Graco Paint Sprayer, ensure the Prime/Spray Valve is in the PRIME position (pointing down). Check the inlet screen for clogs and make sure the suction tube is fully immersed in the fluid. If you haven't already, prime the pump with water or a solvent-based flushing fluid. If the inlet valve check ball is stuck, try dislodging it by inserting a pencil into the inlet section or by power flushing the sprayer. Also, inspect the suction tube for leaks and tighten the connection if necessary. For viscous fluids, momentarily turn off the power switch so the pump can slow and stop; repeat if needed.

Why Graco MAGNUM LTS 15 257060 pump cycles but no pressure?
- B
  Bradley NealAug 22, 2025
  If your Graco Paint Sprayer pump cycles but doesn't build up pressure, start by priming the pump. Ensure the inlet screen is free from clogs and that the suction tube is fully immersed in the paint. Also, inspect the suction tube for any leaks, tightening the connection or replacing the tube if necessary.

  Curtis RandallAug 26, 2025
  If your Graco Paint Sprayer suddenly stops spraying, check the suction tube connection and tighten it if loose, inspecting for any cracks or vacuum leaks. Additionally, the spray tip might be clogged, so unclog it.

Why Graco MAGNUM LTS 15 257060 motor does not run?
- V
  Vernon ReeseAug 28, 2025
  If your Graco Paint Sprayer's motor isn't running, several factors could be at play. First, check that the pressure isn't set to zero; if it is, turn the pressure control knob clockwise to increase the pressure setting. Also, make sure the electric outlet is providing power by testing it with another device or trying a different outlet. Reset the building circuit breaker or replace the fuse if necessary. Inspect the sprayer's electric cord and the extension cord (if used) for any damage, replacing them if needed. Finally, if the sprayer was exposed to freezing temperatures, ensure that any frozen paint or water thaws completely before use. If the paint has hardened, the pump packings, valves, drivetrain, or pressure switch may need replacement.

What to do if Graco MAGNUM LTS 15 257060 Paint Sprayer only dribbles paint?
- C
  Cathy EspinozaAug 31, 2025
  If your Graco Paint Sprayer only dribbles or spurts paint when triggered, start by checking the pressure setting and slowly turn the Pressure Control Knob clockwise to increase it. A clogged spray tip, InstaClean fluid filter, or spray gun fluid filter can also cause this issue; clean or replace these filters as needed. Lastly, verify that the spray tip isn't too large or worn, and replace it if necessary.

Why Graco MAGNUM LTS 15 257060 Paint Sprayer has bad spray pattern?
- A
  acollierSep 2, 2025
  If your Graco Paint Sprayer can't achieve a good spray pattern even at maximum pressure, first check that the reversible spray tip is in the SPRAY position. If it's in the UNCLOG position, rotate the arrow-shaped handle to point forward. The spray tip might be too large for the sprayer or worn out, so try selecting a smaller or new spray tip. Also, ensure the inlet screen, InstaClean fluid filter and spray gun fluid filter are clean. Thin the material if it is too thick, and remove any extra sections of hose if added. Check the pump valves for wear or debris: prime the sprayer with paint, trigger the gun momentarily, and when released, the pump should cycle and stop; continuous cycling indicates worn valves.

Why Graco Paint Sprayer motor gets hot?
- D
  Daniel YorkSep 5, 2025
  If your Graco Paint Sprayer motor is hot and runs intermittently, ensure that the vent holes in the enclosure are not blocked by obstructions or overspray, and keep the sprayer open to air. Replace the extension cord if it is too long or not a heavy enough gauge. If using an electrical generator, make sure it has a proper voltage regulator and provides 120VAC, 60 Hz, 1500 Watts.

Why is Graco MAGNUM LTS 15 257060 Paint Sprayer paint running?
- I
  Isaiah TaylorSep 8, 2025
  If paint runs down the wall or sags when sprayed with your Graco Paint Sprayer, it means the coat is going on too thick. Try moving the gun faster, choosing a tip with a smaller hole size or a wider fan, and ensuring the gun is far enough from the surface.
